Connector and semiconductor test device

Abstract

A connector includes a signal terminal, an insulating member, a ground terminal and an enclosure. The signal terminal has a main body extending in one direction, and a contact arm provided on each side of the main body for contacting another conductor. The insulating member encloses the main body. The ground terminal has a cylindrical main body enclosing the insulating member, and a contact arm provided on each side of the cylindrical main body for contacting another conductor. The cylindrical main body includes first and second semi-cylindrical parts, each having semi cylindrical shapes. The semi-cylindrical parts make a cylindrical shape as a whole by both end parts of the circumferential direction being assembled so as to mutually overlap. An insertion hole is formed in the enclosure where an assembly of the signal element, the insulating member and the ground terminal are inserted.

What is claimed is: 
     
       1. A connector, comprising:
 a signal terminal having a main body that extends in one direction and a contact arm provided on each side of the extension direction of the main body for contacting another conductor; 
 an insulating member arranged so as to enclose the main body part of the signal terminal; 
 a ground terminal having a cylindrical main body of a cylindrical shape arranged so as to enclose the insulating member, a contact arm provided on each side of the center axis direction of the cylindrical main body for contacting another conductor, wherein the cylindrical main body includes a first semi-cylindrical part and a second semi-cylindrical part having semi-cylindrical shapes, and the first semi-cylindrical part and the second semi-cylindrical part make a cylindrical shape as a whole by both end parts of the circumferential direction being assembled so as to mutually overlap; and 
 an enclosure having an insertion hole formed where an assembly of the signal element, the insulating member, and the ground terminal are inserted. 
 
     
     
       2. The connector of  claim 1 , wherein the first semi cylindrical part fits with the insulating member in a flexibly deformed state such that the gaps of both end parts of the circumferential direction are widened. 
     
     
       3. The connector of  claim 2 , wherein the second semi cylindrical part fits with the insulating member that is fit with the first semi cylindrical part, in a flexibly deformed state such that the gaps of both end parts of the circumferential direction are widened. 
     
     
       4. The connector of  claim 3 , wherein a slope is provided on the inner side of the insertion hole of the enclosure that guides at least one of the first semi cylindrical part or the second semi cylindrical part as the insertion of the assembly advances so that the gaps of the mutual center parts of the circumferential direction of the first semi cylindrical part and the second semi cylindrical part narrow. 
     
     
       5. The connector of  claim 4 , wherein the slope contacts the first semi cylindrical part and guides the first semi cylindrical part towards the second semi cylindrical part. 
     
     
       6. The connector of  claim 5 , wherein a stopper is provided on the inner side of the insertion hole of the enclosure that regulates the movement of the second semi cylindrical part to the first semi cylindrical part. 
     
     
       7. The connector of  claim 6 , wherein a pawl part that penetrates into the stopper is provided on both end parts of the circumferential direction of second semi-cylindrical part. 
     
     
       8. The connector of  claim 7 , wherein the contact arm is provided on the part that overlaps the second semi cylindrical part of the first semi cylindrical part and can be flexibly deformed to the outer side of the diameter direction. 
     
     
       9. The connector of  claim 8 , wherein a raised part provided on one of an outer circumference surface of the insulating member or an inner circumference surface of the first semi cylindrical part is fitted into a recessed part provided on the other. 
     
     
       10. The connector of  claim 9 , wherein the insulating member is integrally molded with the signal terminal. 
     
     
       11. A performance board, comprising the connector of  claim 1 . 
     
     
       12. A motherboard, comprising the connector of  claim 1 . 
     
     
       13. A semiconductor test device, comprising the connector of  claim 1 .
